V6R VRF 50/60Hz

8.5 Low Noise Mode

Low noise mode is used to decrease the noise produced by outdoor units. There are 3 kinds of low noise mode: night silent
mode, silent mode and super silent mode. When low noise mode activating, both the fan step and compressor are limited.
In order to maintain the reliability of V6R system, the lowest fan step for inverter module temperature protection is prior to
low noise control.
